On The Partridge Family, Madden's character was oftentimes aggravated by the antics of the onscreen family's children -- particularly by redheaded terror Danny, who was played by Danny Bonaduce, now 54.

Bonaduce tweeted Thursday evening, "Dave Madden was a great guy & like family to me. He taught me to drive a car when I was 10. One of many great memories. I'll truly miss him."

In his lifetime, Madden also served in the United States Air Force, Special Services. According to his IMDb page, he once performed a magic show back in the '50s for King Idris I of Libya, the ruler at the time.

After The Partridge Family ended in 1974, the actor went on to land a role in classic sitcom Alice. He also made guest appearances on later shows shows like Starsky and Hutch, Sabrina, the Teenage Witch (as Dr. Hans Egglehoffer) and Boy Meets World. His final acting credit was voiceover work in 2000's Adventures in Odyssey: The Last Days of Eugene Meltsner.
